"If you are 0/2 before we finish our first clear we arent going to help you. You are a lost cause."
Untrue. Completely urban myth bullshit. I think you forget that this is a game agains people, who can be tricked and outplayed, not to mention they aren't perfect and can mess up. To say 0/2 or /3 is a lost cause is saying that you are okay with how fed the enemy lane gets, which is near invetitable , and you are HOPING that whatever actions you take will compensate for that, which are no were nearly as inevitable as far as success rate goes.
""I could gank for the 0/3 Darius top and die to the 3/0 fiora with a black cleaver at 10min in...... or i could gank for our 1/0/0 syndra mid and get her further ahead so we can shut down the fiora later in the game"
I mean, you are arguing against yourself here. Do you REALLY think that you er going to get you mid outfed over that fiora? In your heart of hearts, you know that you rarely are going to help that mid catch up to the already 3 kills fiora has, and what she is sure to get later on.
I know league players like to regurgitate ideas they hear, but really, just analyze your matches and think about this. All of what you said may be good and true in a vacuum, with teammates and organization and communication. But in solo que, I disagree 110%.
